Keep Change Flip!!!
Keep: the first fraction 5 or 5/1
Change: Division sign to multiplication sign
Flip (reciprocal): the second fraction
So you get 5/1*9/2= 45/2 which simplified to 22 1/2
Even function: f(-x) = f(x). If you replace x by -x you should find the same function.
Odd function: f(-x) = -f(x). If you replace x by -x you find the same function with opposite sign;
Is f(-x) = f(x)?
f(x) = (x+4)² = x² + 8x +16
f(-x) = (-x+4)² = x² - 8x + 16, then it's not an even function
Is f(-x) = -f(x)?
f(-x) = (-x+4)² = x² + 8x + 16 , then it's not an odd function
It is neither an even nor an odd function
Step-by-step explanation:
First we have to same the bases.
As we know 8=2^3.
Replace 8 with 2^3.
Like this .
2^3x=2^3(2x+1).
Now 3x=3(2x+1) distribute 3 by the Barker.
3x=6x+3.
6x+3=3x.
6x-3x=-3.
3x=-3.
X=-1.
Winston would need to sell 14 more hot dogs to earn $175
Step-by-step explanation:
The given is:
- Winston earns $140 by selling 56 hot dogs
- He is using the same rate for the cost of one hot dog
- He want to earn $175
We need to find how many more hot dogs would Winston need to sell to earn $175
∵ The he sold 56 hot dogs for $140
- Find the price of each hot dog by dividing 140 by 56
∴ The price of each hot dog = 140 ÷ 56 = 2.5
∴ The price of each hot dog is $2.5
∵ He need to earn $175
∵ He sells all hot dogs by the same price
- Divide 175 by 2.5 to find the number of the hot dogs
∵ 175 ÷ 2.5 = 70
∴ He must sell 70 hot dogs to earn $175
∵ He already sold 56
- Subtract 56 from 70 to find how many more hot dogs he
needs to sell
∵ 70 - 56 = 14
∴ He must sell another 14 hot dogs to earn that money
Winston would need to sell 14 more hot dogs to earn $175
